Скачать или смотреть Random File Access in C++ - Demo and Explanation

In this video, we will explore the concept of random file access in C++ and provide a comprehensive demonstration to help you understand it better.

Random file access refers to the ability to read from or write to specific locations within a file rather than sequentially from the beginning to the end. It offers great flexibility when dealing with large data sets or when you need to modify specific records within a file without rewriting the entire file.

During this demonstration, we will build a C++ program that showcases random file access in action. We will start by explaining the necessary file handling concepts, such as opening a file, reading from a file, and writing to a file. We'll also cover the importance of error handling and closing files properly.

Next, we'll dive into the implementation of random file access. You'll learn how to position the file pointer at a desired location within the file and perform read or write operations at that precise location. We'll demonstrate how to retrieve specific records, update data, and append new records to an existing file using random access techniques.
